Description

Technical Field

[0001] The present invention belongs to the technical field of noodle production machinery, and particularly relates to a coarse grain noodle extruder. Background Art

[0002] When producing traditional noodles and instant noodle cakes, there are usually two forms: fried and non-fried. In the fried form, the general process is to first cut into strips and then carry out the process of frying and puffing; while in the non-fried form, an extrusion molding process is mostly adopted. However, because coarse grains have lower gluten strength and toughness than fine grains and are not easy to form into groups, with the existing extrusion equipment, since the pressure cannot reach the design requirements, only fine grains such as refined flour (such as white flour) can be produced and processed, and coarse grains cannot be processed, and only raw noodles can be processed. Summary of the Invention

[0003] In order to solve the above problems, the present invention further provides a coarse grain noodle extruder.

[0004] The technical solution adopted by the present invention is as follows:

[0005] The coarse grain noodle extruder includes at least one extrusion assembly. The extrusion assembly includes a driving motor, an auger, and an extrusion barrel; the auger is coaxially arranged in the extrusion barrel, the auger is driven by the driving motor, the blades of the auger are arranged in close contact with the inner wall of the extrusion barrel, and a plurality of inwardly concave rifling grooves are formed in the inner wall of the extrusion barrel along its axial direction, and the plurality of rifling grooves are arranged in a circumferential array. The upper end of the side wall of the extrusion barrel is provided with a feed inlet communicating with the inner cavity of the extrusion barrel.

[0006] The present invention has the following beneficial effects compared with the prior art:

[0007] By closely fitting the blades and the extrusion barrel, the extrusion pressure is increased, and high-temperature circulating water is provided through the water jacket to increase the temperature inside the extrusion barrel, so as to achieve the purpose of high pressure and high temperature. The rifling grooves are used to increase the fusion degree of coarse grains, and at the same time, the purpose of noodle ripening is achieved during the forming process.

[0008] The present invention realizes the non-fried processing of coarse grain noodles and instant noodle cakes. Brief Description of the Drawings

[0012] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 , Figure 2 As shown, the coarse grain noodle extruder of the present invention comprises at least one extrusion assembly, which comprises a driving motor, an auger 4 and an extrusion barrel 2; the auger 4 is coaxially arranged in the extrusion barrel 2, the auger 4 is driven by the driving motor, and the twisted blade 401 of the auger 4 is arranged in contact with the inner wall of the extrusion barrel 2, thereby increasing the extrusion pressure in the extrusion barrel 2 and improving the fusion degree of the coarse grains. At this time, the driving motor is driven by a high-horsepower motor, and the inner wall of the extrusion barrel 2 is provided with a plurality of inwardly concave riflings 202 along its axial direction, the cross section of the riflings 202 is rectangular, and a plurality of the riflings 202 are arranged in a circumferential array. In the process of rotating and extruding with the auger 4, the coarse grains can be completely fused through the scraping of the riflings 202, thereby improving the forming effect and taste of the coarse grain noodles and instant noodles. The upper end of the side wall of the extrusion barrel 2 is provided with a feed port 201 connected to the inner cavity of the extrusion barrel 2. The feed port 201 is arranged at the rear of the upper end side wall of the extrusion barrel 2. A water jacket is provided on the wall of the extrusion cylinder 2, and the water jacket is connected to a water inlet pipe 5 and a water outlet pipe 6. The water inlet pipe 5 is connected to a high-temperature water source, and the temperature in the extrusion cylinder 2 is maintained at 100° C. by constant temperature circulating water through the water inlet pipe 5 and the water outlet pipe 6. The high temperature is used to ensure the maturity of coarse grain noodles and instant noodles.

[0014] During operation, the coarse grain mass transmitted from the mixing process enters from the feed port 201 of the extrusion barrel 2, is squeezed by the twisting blades 401 and the extrusion barrel 2, scraped by the rifling 202, and subjected to high-temperature heat transfer in the water jacket, is gradually cooked and formed at the discharge port of the extrusion barrel 2.

[0015] A pressure gauge 3 is installed on the water inlet pipe 5 .

[0016] The twist blade 401 of the auger 4 and the extrusion cylinder 2 are both made of 306 steel to ensure the strength of the extrusion assembly.

[0017] The driving motor is arranged in the chassis 1 .

[0018] When the number of the extrusion assemblies is four, two extrusion assemblies are arranged side by side at the top and the bottom.

[0019] The auger 4 extends out of the discharge end of the extrusion cylinder 2 , and the feed port 201 of the lower extrusion cylinder 2 is arranged just below the discharge end of the upper extrusion cylinder 2 .

[0020] Two sets of upper and lower extrusion components are set up to perform two aging and molding processes for better results.
